Embodiment Construction
[0013] Non-limiting examples of the present invention are as follows:
[0014] A kind of silicon chip texturizing agent containing kelp extract is prepared from the component raw materials of following weight (kg):
[0015] Kelp powder 10, sodium tripolyphosphate 5, sodium hydroxide 2.5, sodium diisooctyl succinate sulfonate 1, sorbitan monooleate 0.5, amino trimethylene phosphonic acid 0.1, texture regulator 10 , sodium benzoate 0.5, water 150;
[0016] Wherein the texturizing regulator is made of the following component raw materials by weight (kg): styrene 3, methyl methacrylate 2, polyvinyl alcohol 2, cornstarch 1, potassium persulfate 0.1, flat plus 0.5, water 80; The preparation method of the texture regulator is to add polyvinyl alcohol and corn starch to 1 / 2 amount of water and stir at 60°C for 1 hour, then add Pingpingjia and stir for 5 minutes at 1000r / min, add styrene, methyl methacrylate and potassium persulfate Mix well and heat to 85°C to react for 0.5h, and fi...
